List-I | List-II |
A. Metacentric chromosome | I. Chromosome has a terminal centromere |
B. Sub-metacentric chromosome | II. Middle centromere forming two equal arms of chromosome |
C. Acrocentric chromosome | III. Centromere is slightly away from the middle of chromosome resulting into two unequal arms |
D. Telocentric chromosome | IV. Centromere is situated close to its end forming one extremely short and one very long arm |
The correct matches are:
A. Metacentric chromosome - II. Middle centromere forming two equal arms of chromosome.
